Unexpected Error

Active member

After backuping up my site last night I wake up this morning to find a unexpected error in database. I contacted server peeps.

In server it shows 0.14MB for database, the database that I took last night was 13.5MB. Came out twice the samething.

Well site was working fine when I went to bed at 1am now at 8am and after two hours with server peeps they say database is corrupt! I tried to do a restore of last night and it had critical error on it. I did another restore that I had and it took me back to I think now before I did the update to the candidate 2

Why?

I have the database here why is it all the sudden corrupt and I lost many post?
